Fluid applicators for use with topical medications

An apparatus, comprising:

• a housing;
• a fluid containment system disposed inside the housing, the fluid containment system including a cage and a fluid container disposed inside the cage, the cage including a ramp;
• a pump assembly disposed inside the housing and fluidly coupled to the fluid containment system;
• an applicator coupled to a first end of the housing, the applicator defining an outlet and having a surface to be in contact with an application site on a person, the surface in fluid communication with the pump assembly via the outlet;
• and
• a one-way actuator rotatably coupled to a second end of the housing opposite the first end, the actuator to engage the ramp, wherein rotation of the actuator in a first direction from a first position to a second position is to move the cage toward the applicator via the ramp, and rotation of the actuator in the first direction from the second position to a third position is to move the cage away from the applicator, at least one of movement of the cage toward or away from the applicator is to operate the pump assembly to dispense a dose of the fluid onto the surface.

An apparatus, comprising:

• a housing;
• a cage disposed inside the housing and slidably coupled to the housing;
• a pouch disposed in the cage;
• a pump disposed in the housing, the pump in fluid communication with the pouch;
• an applicator fixedly coupled to the housing, the applicator having a surface in fluid communication with the pump via an outlet defined by the applicator, the surface to contact an application site on a person to transfer the fluid from the surface to the application site;
• and
• an actuator rotatably coupled to the housing, the actuator including a protrusion to urge the cage toward the applicator to cause the pump to dispense a portion of the fluid onto the surface.

An apparatus, comprising:

• a housing;
• an applicator including a surface defining an outlet;
• a fluid container disposed inside the housing and slidably coupled to the housing, the fluid container to store a fluid;
• a ramp coupled to the fluid container;
• a pump disposed inside the housing;
• and
• an actuator rotatably coupled to the housing to engage the ramp, rotation of the actuator to slide the fluid container relative to the applicator via the ramp to actuate the pump to pump the fluid from the fluid container, the fluid to be supported on the surface.
